Re: [twsocket] TSmtpClient Exception handling
Hello The problem seems to be solved (more or less). It only occurs if the application is started from a network drive and the connection to that drive is cut. I'm not sure where the problem is exactly but all other accesses to the network do not result in this kind of desaster. Anyway: Not a problem of ICS anymore.

Do you run the application in debugger? That would show you the line where the exception (if any) was raised.

[twsocket] TSmtpClient Exception handling
Hi I'm currently testing my usage of TSmtpClient and I get some strange behavior: When I unplug my computers network cable while a SMTP connection is active it takes about 5 to 10 seconds and then a MessageBox-like window appears with the Error Icon but no test at all on it. Ignoring the fact that my program is now frozen, where does this window come from and how can I handle a hard disconnect like this gracefully?
